Question

P agreed to buy 100 barrels of widget oil, which was stored in a large tank at D’s depot. The tank contained a total of 10,000 barrels of widget oil. Before separating and barrelling P’s oil, the equivalent of 1,000 barrels of oil leaked from D’s tank. D then refused to deliver to P, claiming that the 1,000 barrels that leaked included her 100 barrels and that she would have to bear the loss. When P refused to pay, D wishes to sue her for the price. Discuss. An analysis of this question, using a problem-solving approach.
